    Dr. Sang-Woo Kim of Institute Of Nanotechnolgy at Sungkyunkwan University in South Korea has been developing a design to harvest energy from sound waves. Zinc Oxide sandwitched between electrodes has produced promising results and could convert sound of about 100 dB to generate 50 mV of electricity. But this energy is not enough to charge your phone. For more information, read: <a href="https://www.telegraph.co.uk/technology/news/8500161/Mobile-phones-could-be-charged-by-the-power-of-speech.html" target="_blank" rel="noopener noreferrer">Mobile phones could be charged by the power of speech</a>

    A lot of work needs to be done on this front. If you have any ideas to achieve this, do share them with us.

    100dB is too loud that it can damage the ear if exposed for longer period of time.
    Hence, Fail!

    சும்மா இருப்பதே சுகம். Silence is golden.
    Many decades back there was a report that the total enregy of all the lectures by a senior professor in a year was worth ten cents.

    You will conserve battery charge more by minimising unnecessary speech on the mobile. There just is not enough energy in speech especially on the mobile.
